HP StorageWorks EVA Cluster Extension Software Administrator Guide (T3667-96045, April 2010)

When configuring EVA Cluster Extension resources, note the following:
• If the Cluster Administrator or Failover Cluster Management GUI is used to configure an EVA
Cluster Extension resource, configuring the resource using a user configuration file (UCF file) is
not required.
• EVA Cluster Extension creates a file called resource_name.online to indicate that the EVA
resource is online on the local node. This file is created in the directory specified by the Applica-
tionDir resource property. If the resource is taken offline, this file is deleted.
• Two required property values can be set automatically only through the Cluster Administrator/Fail-
over Cluster Management GUI or the EVA Cluster Extension resource configuration tool. The values
of CSObjectPathA and CSObjectPathB are gathered and set by clicking the OK or Apply button
in the Parameters tab of the GUI. To set these properties using the CLI, use the clxconf command
and configure a UCF.cfg file. For more about the clxconf command, see “clxconf” on page 91.
• Windows Server 2008/2008 R2 only: If an EVA Cluster Extension resource is not configured,
the resource icon in the Failover Cluster Management GUI shows the message “not configured”
next to the resource status.
• The EVA Cluster Extension resource must be the first resource for all other disk resources.
• The resource's PendingTimeout value must be equal to or greater than the value specified for the
ResyncWaitTimeout attribute.
• The resource's PendingTimeout value must be equal to or greater than the wait time specified for
the SmisRequestTimeout value.
Setting Microsoft cluster-specific resource and service or application properties
Microsoft allows you to set specific failover parameter and threshold values for a service or application,
as well as for a resource. Some of these values must be changed for EVA Cluster Extension to enable
manual recovery actions in case of a disaster.
To set Microsoft cluster-specific resource properties:
• For Windows Server 2003, use the Cluster Administrator GUI or cluster commands in the CLI.
• For Windows Server 2008/2008 R2, use the Failover Cluster Management GUI or cluster com-
mands in the CLI.
• For Server Core or Hyper-V Server, use cluster commands in the CLI.
TIP:
You can use the GUI option for Server Core or Hyper-V Server by using the MMC to manage a
cluster remotely. For more information about using the MMC, see your Microsoft documentation.
EVA Cluster Extension requirements for Cluster Administrator and Failover Cluster Management
resource properties are described in Table 1 on page 34. If there is no required value for a property,
the valid and/or default values are specified. Set these properties in the resource properties window
or the CLI. If you use the CLI, use the following command:
cluster.exe resource ResourceName /prop PropertyName="PropertyValue".
